Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
[4] [5] [6] Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. [ 7 ] The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology , while parasitology refers to the scientific ...
The first article to propose Morgellons as a new disease in a scientific journal was a review article co-authored by members of the MRF and published in 2006 by the American Journal of Clinical Dermatology. [25] A 2006 article in the San Francisco Chronicle reported, "There have been no clinical studies" of Morgellons disease. [25]

Viruses [66] are the usual infectious agents that cause cancer but bacteria and parasites may also play a role. Oncoviruses (viruses that can cause human cancer) include: Human papillomavirus (cervical cancer), Epstein–Barr virus (B-cell lymphoproliferative disease and nasopharyngeal carcinoma),
This is the only member of this group of viruses known to cause human cancer but other polyomaviruses are suspects for being additional cancer viruses. [citation needed] HIV does not directly cause cancer, but it is associated with a number of malignancies, especially Kaposi's sarcoma, non-Hodgkin's lymphoma, anal cancer and cervical cancer.
AGS can cause a range of symptoms: mild ones like a rash or hives, or more severe ones such as difficulty breathing, and even anaphylaxis, says infectious disease expert Amesh A. Adalja, M.D ...
Clinical and toxicological research conducted on volcanic crystalline silica has found little to no evidence of its ability to cause silicosis/pneumoconiosis-like diseases and geochemical analyses have shown that there are inherent factors in the crystalline structure which may render volcanic crystalline silica much less pathogenic than some ...
